World's First Programmable Nanoprocessor

While Studying at University, I had an opportunity to take up Nanotechnology as a Subject for my Final Year. I was also part of the Team which put up the First Nano Stall in Sri Lanka. Coming to the topic, No Microprocessors, Its *Nanoprocessors*.


ALU functionalities performed at Atomic scale. That's right!!!

1 nm ~ 10 * (width of Hydrogen Atom)

This Work done by Researchers at Harvard University and MITRE's Nanosystems Group. They have come up with Detail Architecture of Programmable Nanoprocessor built out of Nanowires.

As many of you don't know, Nanotechnology has come a long way and It is usually has Top-Down or Bottom-Up approach. Mostly Top down approach is used where you use Chemical Reactions at Nanoscale to form up the required Functionality.

But the difficult and still at research level is the Bottom-Up Approach. It is the Concept of building anything from Atom by Atom. Forming a full structure from atoms.

"This new nanoprocessor represents a major milestone toward realizing the vision of a nanocomputer that was first articulated more than 50 years ago by physicist Richard Feynman." says James Ellenbogen, a chief scientist at MITRE
